> NPE while establishing the root subsystem
> -----------------------------------------
>
> Key: ARIES-990
> URL: https://issues.apache.org/jira/browse/ARIES-990
> Project: Aries
> Issue Type: Bug
> Components: Subsystem
> Reporter: Thomas Watson
> Assignee: John Ross
>
> I got the following NPE while the subsystem core was activating and
> establishing the root subsystem. I think at the time many bundles in the
> 'root' subsystem may have been getting deleted:
> >Caused by: java.lang.NullPointerException
> > at
> > org.apache.aries.subsystem.core.internal.ResourceHelper.getIdentityAttribute(ResourceHelper.java:62)
> > at
> > org.apache.aries.subsystem.core.internal.ResourceHelper.getTypeAttribute(ResourceHelper.java:92)
> > at
> > org.apache.aries.subsystem.core.internal.ResourceInstaller.newInstance(ResourceInstaller.java:27)
> > at
> > org.apache.aries.subsystem.core.internal.Subsystems.populateRootSubsystem(Subsystems.java:173)
> > at
> > org.apache.aries.subsystem.core.internal.Subsystems.getRootSubsystem(Subsystems.java:131)
> There is a TODO in Subsystems.populateRootSubsystem that I think is showing
> itself in this NPE. In the following line of code the bundle revision may be
> null if the bundle got uninstalled:
> BundleRevision revision = bundle.adapt(BundleRevision.class);
> I think a check for null is needed here.
